Examples

The following example demonstrates how to use the CurrentItem property to make changes when an item is selected. It assumes that you have a form that contains a bound DataRepeater named DataRepeater1, a bound TextBox named UnitsInStockTextBox, and a Label named LowStockWarningLabel.

Private Sub DataRepeater1_CurrentItemIndexChanged(
  ) Handles DataRepeater1.CurrentItemIndexChanged

    ' Exit if the control is first loading. 
    If DataRepeater1.CurrentItem Is Nothing Then Exit Sub 
    ' Check for zero or negative quantity. 
    If CDbl(
        DataRepeater1.CurrentItem.Controls("UnitsInStockTextBox").Text
       ) < 1 Then 
        ' Display a the warning label on the form. 
        Me.LowStockWarningLabel.Visible = True 
    Else 
        Me.LowStockWarningLabel.Visible = False 
    End If 
End Sub

private void dataRepeater1_CurrentItemIndexChanged(object sender, System.EventArgs e)
{
    // Exit if the control is first loading. 
    if (dataRepeater1.CurrentItem == null) { return; }
    // Check for zero quantity. 
    if (dataRepeater1.CurrentItem.Controls["unitsInStockTextBox"].Text == "0") 
    // Display a the warning label on the form.
    {
        this.lowStockWarningLabel.Visible = true;
    }
    else
    {
        this.lowStockWarningLabel.Visible = false;
    }
}
